[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0019] Referring to Figures 1-4 , two-position two-way pilot type pneumatic electromagnetic valve, including electromagnetic valve body 1, the one side of electromagnetic valve body 1 is provided with import 11, the bottom of electromagnetic valve body 1 is set up with mounting cavity 12 upwards, mounting cavity 12 is adapted to be assembled with mounting plate 2, and the corresponding import 11 of mounting plate 2 is adapted to be provided with filter screen 21. The bottom of electromagnetic valve body 1 is fixedly provided with fixed seat 3 on one side of mounting plate 2, pull plate 4 is movably provided on one side of fixed seat 3, limiting column 41 is vertically fixedly provided on the two sides of pull plate 4 and is adapted to be provided with limiting cavity 22 on the corresponding limiting column 41 of mounting plate 2.

[0020] The electromagnetic valve body 1 is a two-position two-way pilot type pneumatic electromagnetic valve, which controls the opening and closing of the valve body through the electromagnetic operation part (including the electromagnetic coil, the valve core and the spring). The inlet 11 and the outlet are arranged on the two sides of the electromagnetic valve body 1, and the inner walls of the inlet 11 and the outlet are provided with threads for mounting. It is worth noting that the specific structure of the electromagnetic valve body 1 and its working mode are prior art, so no more description is given.

[0021] The mounting cavity 12 is in communication with the inlet 11, and the outer side of the mounting plate 2 is sleeved with a sealing sleeve. By arranging the sealing sleeve, the sealing performance of the mounting plate 2 inside the electromagnetic valve body 1 during assembly can be improved.

[0022] The two sides of the surface of the fixed seat 3 away from the mounting plate 2 are fixedly provided with guide columns 31 arranged vertically, and the pull plates 4 are guided and moved by the guide columns 31. By arranging the guide columns 31, the stability of the pull plates 4 during movement can be improved.

[0023] The surface of the fixed seat 3 facing the pull plate 4 is provided with a plurality of spring cavities 32 inwardly, the spring cavities 32 are provided with springs 33, and the other ends of the springs 33 are connected with the pull plate 4. By arranging the springs 33, the pull plate 4 can be moved to the mounting plate 2, so that the limiting column 41 can be stably clamped in the limiting cavity 22.

[0024] The bottom of the electromagnetic valve body 1 is fixedly provided with a plurality of side plates 13, and the side plates 13 are provided with side cavities 14 corresponding to the limiting column 41. When the mounting plate 2 is assembled in the mounting cavity 12, the side cavities 14 are aligned with the limiting cavities 22.
